at()

uint8_t Buffer::at ( const size_t  n ) const

inline

Get character at location n

Definition at line 38 of file buffer.hh.

copy()

std::string Buffer::copy ( ) const

inline

Make a copy to a new std::string.

Definition at line 44 of file buffer.hh.

operator std::string_view()

Buffer::operator std::string_view ( ) const

inline

Definition at line 34 of file buffer.hh.

remove_prefix()

void Buffer::remove_prefix

(

const size_t

n

)

size()

size_t Buffer::size ( ) const

inline

Size of the string.
